3d Audio

I'm entering the CMG "Blind" Contest, and I need to use 3d audio (like what Diordna's entry does), but I've yet to find a way to do it. I would think that OpenAL would be promising, but I can't even find an API reference, let alone any samples of it in work. I've also been looking at using Quicktime, but I've yet to find anything that would help me accomplish this.

At least I have NSSpeechRecognition working, and it works great (I want to thank Kelvin for the help he provided on that one).

I just realized that I can probably fake it, by writing my own system. Make a location based system, that adjusts the speaker balance and volume based on the location of the sound relative to the player. Quicktime should allow both volume and speaker balance to be changed, and everything else I can do myself.
